We had a great time. I will give her credit, she puts on a heck of a show. Outstanding stage design; A/V on multiple large screens (not just live shots of the stage); amazing lighting; excellent dancing; I lost track of the number of costume changes, for her and her backup singers/dancers; four separate "lift" units on stage (one elevated cylinder, a pair of trapezes to which dancers connected and lifted Katy at one point, a lift seat at the back of the stage, and a "cloud" that descended from the rafters and carried Katy over the floor to the back end of the area and back); a trap door in the stage through which Katy and dancers descended; smoke effects; a bubble machine; actual indoor fireworks; and at the end of the show a foam cannon (that couldn't quite reach where we were sitting, luckily) and a confetti cannon.
As I said on FB, you are officially the man. Business cards are the beginning. Advertising on your website - you could win a date with the real Smurfette if you book by ...
